nullsink
nullsink is an anonymous API proxy for frontier and open-weight language models, compatible with Anthropic and OpenAI SDKs. Users purchase prepaid keys using cryptocurrency (Monero or Bitcoin) without any sign-up, then point their existing tools at the proxy endpoint. The service operates with a strict no-logs policy: no accounts, email, IP tracking, request logs, cookies, or analytics, ensuring complete privacy. Purchases range from $2 to $100, with keys generated client-side in the browser and paid on-chain. Transactions typically confirm within 20–45 minutes. Once obtained, the key acts as a drop-in replacement for official API keys, making integration seamless for developers already using OpenAI or Anthropic libraries. The proxy handles all model interactions, relaying requests and responses without retaining any user data. nullsink explicitly lists supported models on its site, which include both frontier and open-weight options. The service is still in early access, so brief outages may occur, but it provides a simple, privacy-first alternative for accessing state-of-the-art LLMs. There is no customer support beyond community channels (Discord, Matrix), and payments are final with no refunds. The codebase appears to be open-source on GitHub, enabling transparency and potential self-hosting, though the primary offering is the hosted proxy.
